Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Using FFmpeg, How to convert an frame image sequence to video(video codec : dvvideo) ?
25 mai 2022, par rupingI'm working on an image processing project.


The project proceeds as follows :


Input Video -> frame Sequence -> (Processing) -> Output Video


I want to create the output video with the same specifications as the input video.


The specs of the input video we use are :


- Size : 1280x1080, Codec : dvvideo, pixel_fmt : yuv422



But I am struggling with the following error :


Duration: 00:00:03.20, start: 0.000000, bitrate: N/A
 Stream #0:0: Video: png, rgb24(pc), 1280x1080 [SAR 3:2 DAR 16:9], 29.97 fps, 29.97 tbr, 29.97 tbn, 29.97 tbc
Stream mapping:
 Stream #0:0 -> #0:0 (png (native) -> dvvideo (native))
Press [q] to stop, [?] for help
[dvvideo @ 0x55b965b745c0] DVCPRO HD encoding is not supported.
[dvvideo @ 0x55b965451780] ff_frame_thread_encoder_init failed
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
Conversion failed!



The code is below. (subprocess in python)


ffmpeg -y -f image2 -r "{fps}" -i {input_img_root} -s 1280:1080 -b:v {bit_rate} -vcodec dvvideo -pix_fmt yuv422p "{output}"



(fps and bitrate are taken from the input video. and input_img_root and output are paths.)


I've been trying for several days, but it doesn't work.


If you know any way to make a new video while maintaining the video specifications (Especially dvvideo codec)(not using ffmpeg), it would be nice to share it.

Thank you !

What is the accurate way of calculating SSIM score (with ffmpeg) between a video stream and the reference video ?
22 mars 2016, par krishna222As ffmpeg calculates ssim score by a frame-by-frame comparision,
how do I exactly align the reference video (say ref.mp4) with the video stream, so that only the corresponding frames (ith frame of both the videos, for all i) are compared by ffmpeg ? Please help.
